KELSEYVILLE -- Three properties were searched turning up hundreds of pounds of pot and resulting in four arrests.

The service of a search warrant based on a continued investigation by the Lake County Sheriff's Office (LCSO) Narcotics Task Force resulted in the seizure of the 500 pounds of processed marijuana from one location.

Detectives secured the search warrant on Halloween for a home and property on the 7000 block of Highway 175 in Kelseyville.

On Nov. 1 at approximately 3:30 p.m., detectives served the warrant and contacted and detained Matthew Doyle Roche, 22, of Savannah, GA., Ashley Ryan Sherman, 34, of San Anselmo, Bradley Thomas Taylor, 36, of Whitethorn and Zion John Wooldridge, 36, of Healdsburg, without incident.

During the search, 160 marijuana plants were located along with 500 pounds of processed marijuana inside a barn that was allegedly used as a marijuana processing station.

Roche, Sherman and Taylor were arrested on charges of possession of marijuana for sale. Wooldridge was arrested on charges of possession of marijuana for sale and for committing a felony while out on bail. On Oct. 18, the United States Forest Service conducted a traffic stop on a vehicle driven by Wooldridge, pulling a trailer in the Kelseyville area. Forest Service personnel detected a strong odor of marijuana, which they believed was coming from inside the trailer and proceeded to deploy a narcotic detection K-9 that identified the trailer as the source of the odor. A search of the trailer resulted in the seizure of 109 pounds of processed marijuana.

Wooldridge was arrested by the Forest Service on charges of possession of marijuana for sale and transportation of a controlled substance.

On Nov. 7, 2012 the Lake County Narcotics Task Force assisted the Sonoma County Narcotics Task Force and the United States Forest Service with the service of a search warrant for two more of Wooldridge's residences.

One of the homes was in Santa Rosa and the other was in Sebastopol. An additional 211 pot plants were located in what was described as a "sophisticated marijuana cultivation operation," according to a press release from LCSO.

Wooldridge is in custody at the Lake County Hill Road Correctional Facility. His bail is set at $225,000.
